Thanks for the replies..

but i have some issues here ..

i have a mainfile (backup file) a.txt

and i have a constant file b.txt which will be added or deleted

lets assume i have the following contents in a.txt :

unix:workinshellscripting
samplethings
sample
condition
success
failure

unix:shell
cool
ice
work
place
history

and b.txt has
workinshellscripting

once i run the shell script it should read the param file and read the value in the backup files

and once the string is found it has to copy the contents (5 lines below) and paste it in an output file

hence my outputfile has these

unix:workinshellscripting
samplethings
sample
condition
success
failure

NAME
ixpc - ixp client SYNOPSIS
ixpc [-a address] action file ixpc -v DESCRIPTION
Overview ixpc is a client to access a 9P file server from the command line or from shell scripts. It can be used to configure wmii(1). Options -a address Lets you specify the address to which ixpc will establish a connection. If this option is not supplied, and the environment variable IXP_ADDRESS is set, ixpc will use this value as its address. Currently, the address can only be a unix socket file or a tcp socket. The syntax for address is taken (along with many other profound ideas) from the Plan 9 operating system and has the form unix!/path/to/socket for unix socket files, and tcp!hostname!port for tcp sockets. -v Prints version information to stdout, then exits. The syntax of the actions is as follows: write Writes the supplied data from the standard input to file, overwriting any previous data. The data to be written is arbitrary and only gains meaning (and restrictions) when it is interpreted by wmiiwm(1). See EXAMPLES below. xwrite The same as write, but the data is taken from subsequent arguments, rather than the standard input. create Creates file or directory. If the file exists, nothing is done. ls Lists files and directories. read Reads file or directory contents. remove Removes file or directory tree. ENVIRONMENT
IXP_ADDRESS See above. EXAMPLES
ixpc ls / This prints the root directory of the wmii filesystem, if IXP_ADDRESS is set to the address of wmii. For more information about the contents of this filesystem, see wmiiwm(1). ixpc xwrite /ctl quit Write 'quit' to the main control file of the wmii filesystem, effectively leaving wmii. ixpc write /keys < keys.txt Replace the contents of /keys with the contents of keys.txt SEE ALSO
